speed of fast plane = x mph
\n" ); document.write( "speed of slow plane = (x-70) mph\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "distance between planes after h hours: (2x-70)h miles\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "h = 3 ----> 3(2x - 70) = 870
\n" ); document.write( "2x - 70 = 290
\n" ); document.write( "2x = 360
\n" ); document.write( "x = 180\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "slower plane = 110 mph
\n" ); document.write( "faster plane = 180 mph
\n" ); document.write( "
\n" );
